Patients undergo routine colposcopy as part of their regular colposcopic evaluation. The digital colposcope is used to take images of the vagina and cervix, pre- and post-acetic acid, using white, green, and blue light. Colposcopically abnormal areas are biopsied; a normal area may also be biopsied. Patients undergoing loop electrosurgical excision procedure (LEEP) may undergo one additional biopsy of a colposcopically normal site.
